CLEANING AND SORTING MACHINE FOR GRAIN AND THE LIKE.

Application filed January 27, 1921. Serial No.. 440,4.-55.

ing boxes are known in which between the fan and the shaking boX there is no wall, but the fan 1s, for example, fully enclosed on all the other sides. Devices are also known in which the. fan compartment is open both towards thev shaking box and towards the opposite direction, but the fan itself is placed in an intermediate wall dividing its compartment. The arrangement according to the invent-ion differs from these known devices since the fan has no separate suction and delivery space separated by intermediate walls, but works in a coinpartment open towards the shaking sieve shoe and also in the opposite direction. This arrangement not only gives an essentially higher working efciency, but the current of air is independent of the form and to a large extent also of the size of the fan.

`The latter is only dependent on the form of the opening of the compartment. Instead of the usual form of fan a two or three bladed propeller can in known manner advantageously be used. The same device can also be used with threshing machines or the like. A plate controlling the discharge of the current of air from the fan compartment can be advantageously arranged at the shaking sieve shoe, so as to be adjustable longitudinally, as an extension of one side wall of the fixed charging funnel, so that on the one side it may, in consequence of the shaking movement imparted to it, help the feeding of the material and on the other hand it may control the cross section of the outlet from the compartment and thereby the strength of the current of air.

The accompanying drawing shows an example of a construction according to the invention. Fig. l is a longitudinal and Figure 2 a cross section through the apparatus. Fig. 3 is a detail view showing the adjustable mounting of the fan shaft. Fig. 4; shows a detail.

The cleaning and sorting machine consists of a shaking sieve shoe a in which the sieves o are fastened. The lower sieves c i are rigidly connectedwith the shaking sieve shoe a.. In the fan compartment L there is aY discharge board The drive of the shaking sieve shoe is effected by means of an eccentric d or the like.

The fan g which is secured to the stub shaft f is placed in a compartment It which .has no intermediate walls and is open both towards the shaking sieve shoe 0. and also in the opposite direction (outwards). The control of the air entering the compartment 7e, may be effected by a slide o by means of which the strength of the current of air from the fan to the shaking sieve shoe may be controlled.

Instead of this control, or co-operating with it, according to the invention the current of air produced by the fan g may be controlled at its outlet from the compart-V ment h by means of a plate m which is arranged below the fixed charging funnel Z in the extension of one side wall of the latter so as to be longitudinally adjustable on battens m1 at the shaking sieve shoe (Fig. 5). This plate provided with a corrugated sheet metal covering m forms to a certain extent an extension of this funnel wall and helps the feed by means of the movement imparted to it by the shaking sieve shoe. It can be adjusted so as to control also the cross section of the outlet from the compartment It and therewith the strength of the current of air.

The stub shaft f to which the fan is secured receives its drive from the hand crank 7c by means of gear wheels c', 1, shaft p, bevel wheel 2, and pinion 3. The shaft 29 which carries the gear wheel 1 and bevel wheel 2 is mounted to rotate in bearings carried by one of the side members of the machine and by a member which extends vertically of the compartment h midway of the width and at one end of the latter (here shown at the inlet end). The bearing Zal for the shaft f of the fan is loosely mounted onthe shaft p so as to be angularly adjustable on the latter. Means are provided for securing the bearing 7c in adjusted position. In the resent instance such means is shown as consisting of a sector r extending rearwardly from the bearing f and having a curved slot concentric with the axis of the shaft p', bolts extending from one side of improves the output and at the same time to be used, which place considerably diminishes the power required to work the apparatus. There is also a con` siderable saving of weight in the whole machine, which is,v of considera-ble importance withV respect to the necessary transport of the Whole apparatus to the place where it is must be frequently changed.

What IV claim is l l. A cleaning and sorting machine, comprising shaking sieve shoes, a stationary ian compartment adjacent said shaking sieve shoes open toward the latter and also open inl the opposite direction and closed in all other directions, and a fan in said compartment having its axis adjustable relatively to said shaking sieve shoes.

2I'A cleaning andsorting machine, coinprisingv shaking sieve shoes, al stationary compartment adjacent the shaking sieve shoesy and open toward the latter and also in the, opposite direction'and closed in all other directions, anda fan in said compartrlhe fan ment having its axis angularly adjustable relatively to said shaking sieve shoes.

3. A cleaning andV sorting machine, comprising shaking sieve shoes, `a stationary compartment open at one end toward the shaking sieve shoes and also open at its opposite end and closed in all other directions, a vertical bar at one end of said compartment, and a propeller blade fan having its bearing mounted for angular adjustment on said bar.

4. A cleaning and sorting machine, comprisingkshaking sieve shoes, a stationary fan compartment opposite said shoes having an opening directed toward said shoes and an opening in the opposite direction, a fan within said casing, ashaftrextending transversely into said casing,vmeans on said shaft and on said tan adapted to cooperate to rotate the ian, a shaft for supporting said Jfan having a sector-shapedk member integral therewith andV rotatable about Vsaid first named shaft, said sector-shaped v:member having an arcuate slot therein concentric Vith said rst named shaft, andbolts passing throughsaid slot adapted to secure said second named shaft in various positions of"v angular adjustment about the said first:

named shaft.
